Question

6 A particle is moving in a circular path of
radius r. What will be the displacement
after half a circle? ​

Answer 1

Answer:

Given, after half the circle, the particle will reach the diametrically opposite point i.e., from point A to point 6. ... Hence, the displacement after half circle is 2r.

Answer 2

Explanation:

Displacement at half path is the shortest distance between the initial and final point.

So, it's equal to twice the radius of the circle =2r
